G. H. Horn's " Synopsis of the Histeridae of the United States " (P. 
Am. Phil. Soc. xiii. No. 91, pp. 273-360, pi. v.), is practically a re-revision 
of Leconte's paper on the same subject. The author divides the genera 
into two tribes : Hololeptini, with head porrected and mandibles very 
prominent, and Histnni, with head retracted and deflexed, and not very 
prominent mandibles. Lionota is united to Hololepta. The Histrini are 
again divided into Histrini and Saprini\ni\ Bacanius being removed 
from the former and placed near Acritus. Psiloscelis, Margarinotus, 
Hister, Pkelister, Platysoma, and Ci/listix, are dubiously treated as sub- 
genera, the species of Hister being grouped under the names of typical 
and common forms ; Gnathoncus and Pacliylopus are merged in Saprinm.

All Histeridce are probably carnivorous. Hister lielluo attacks larvae of 
Agelastica, H. pustulosvs those of Agrotis. E. Reveliere, Nouv. et faits,
